Country music star Riley Green has officially made his acting debut in the CBS series Marshals, a spin-off of the Yellowstone universe, marking a major career shift as he takes on a dramatic new role far removed from his music persona.

Green appears as Garrett, a former U.S. Navy SEAL and troubled ex-comrade of lead character Kayce Dutton, introduced in the series during a storyline that explores trauma, military fallout, and unresolved conflict from their shared past, according to production details of the show Marshals.

The character’s arrival is portrayed as a disruptive force within the Marshals unit, reopening old wounds between former teammates while tying into the show’s broader investigation-driven narrative. Garrett is also depicted as struggling with psychological scars from his military service, a central theme in his introduction to the series.

Green’s casting marks his first professional acting role, following a career in country music where he built a strong fanbase through touring and multiple studio albums. His transition into television has been closely watched by fans of both his music and the expanding Yellowstone franchise Yellowstone.

The debut episode featuring his character has already sparked strong reactions from viewers, with early audience responses focusing on the darker tone of his role and how it integrates into the ongoing storylines of the Marshals team.

Producers have hinted that Garrett will continue to play a recurring role, suggesting his storyline will develop further as the season progresses, potentially deepening existing tensions within the unit and connecting to unresolved events from the team’s past operations.
